Thread: D4 Tyre pressure for sand driving with 19"

Doc,

I did Fraser in March in my D4 with 19" Scorpions. I ran 20 psi and had no problems on the beach but I did manage to fatally damage two tyres on the inland tracks.

In the last 9 years I've never had any tyre problems or damage up there but the difference this time around was the 19" tyres. My previous D4 and the D3 before that ran 18" and at 20 PSI or less they worked well.

I think the side walls on the 19" bulge a lot more than the 18" so next time I'll be running at >25 or so on the tracks and only going down to 20 or so when really needed.

Cheers.

Sounds about right for a P construction tyre.
I'm looking forward to reports from those tuning the Maxxis LT in 19". With its stronger sidewalk construction it should fare a lot better at 20psi

Is my tyre an LT or a P?

Duratrac is not an LT.
S speed rating
111 load rating

Cheers,

We ran 17psi the whole weekend - you do need to pay attention on the tracks for roots but max speed is 30 anyway. It's interesting to watch the tyres on the D4 in front of you - you can really see the benefits of lower pressures

I am too running 19" rims with Duratrac 255/55/r19. We are heading to Stokton tomorrow thinking I might start at 20 psi

The Duratracs are XL rated, with only the Maxxis Bravo 980 being LT
